This protocol is used to measure sodium currents from heterologously transfected cells lines, such as HEK293 cells. Standard whole cell patch clamp technique is used to assess ion channel function. This protocol has been used to study cardiac type Na ...

A great way to specifically isolate and quantify proteins in the cell surface membrane is to take advantage of the biotinylation technique. It consists of labeling cell surface proteins with a biotin reagent before lysing the cells, and isolating ...
